    Hub Device for Universal Serial Bus
    The present invention relates to a hub device of a universal serial bus, and more particularly, to a universal serial bus that can be used both as a bus-powered device and a magnetic-powered device, and to prevent jitter that may occur during power switching. It relates to a hub device.
    Generally, a hub is a device that can connect a plug wire to transmit a signal to a socket on a control panel or a plug board, and distributes and distributes signals to different ports (Port 1 to Portn). There are bus powered hubs and magnetic powered hubs.
    1 is a block diagram showing a configuration of a hub device of a universal serial bus having a conventional bus power, and as illustrated therein, a PC 10 for overall control of input and output of data and power; The hub 11 receives data and power from the PC 10 and supplies the same to the plurality of ports Port1 to Portn by a predetermined control signal of the controller 12. Explain.
    First, the hub 11 functions as one multi-tap function, that is, receives data and power from the PC 10 and inputs / outputs data to a plurality of ports (Port1 to Portn) by a control signal of the controller 12. To make it possible.
    In addition, the hub 11 has a tab to which other devices can connect to each port (Port1 to Portn), and when the connected device needs power, the PC 10 is controlled by the control signal of the controller 12. Receive power from and supply it to the devices connected to each port
    However, such a conventional device is a hub of one universal serial bus, so a universal serial bus device having bus power and a serial bus device having magnetic power cannot be implemented at the same time. All devices connected to and used in the system should be basically the same power system, and there was also a problem that jittering may occur during power switching.
    Therefore, the present invention devised in view of the above problems can be used both as a bus-powered device and a magnetic-powered device, and it is possible to prevent the jitter that may occur during power switching. The object is to provide a hub device.
    1 is a block diagram showing a configuration of a hub device of a conventional universal serial bus.
    Figure 2 is a block diagram showing the configuration of a hub device of the present invention universal serial bus.

    1 to n: control unit
    An object of the present invention for achieving the above object is a PC that controls the input and output of data and power; It is characterized by consisting of a hub for supplying a different power to the PC data and a plurality of ports.
    Hereinafter, with reference to the accompanying drawings the operation and effects of an embodiment of a hub device of a universal serial bus (Universal Serial Bus) according to the present invention will be described in detail.
    Fig. 2 is a block diagram showing a configuration of a hub device of a universal serial bus of the present invention, as shown in this embodiment; It consists of a hub 20 for supplying power different from the data of the PC 10 to a plurality of ports (Port1 ~ Portn).
    The hub 20 includes a plurality of controllers 1 to n for controlling different power to be supplied to each of the ports Port1 to Portn when power is applied to the plurality of ports Port1 to Portn.
    The controllers 1 to n connect the switch SW to an output terminal of the buffer BUF at which one side is grounded, and parallel the diode D in a reverse direction to the resistor R to which the power supply voltage VCC is applied at one side. The inverter (IN) is connected to the other side of the resistor (R), the switch (SW) is configured, and the operation of the present invention will be described.
    First, the general operation is the same as in the prior art. That is, the hub 11 has one multi-tap function. That is, the hub 11 receives data and power from the PC 10 and transmits the data to a plurality of ports Port1 to Portn by the control signals of the controllers 1 to n. Enable input and output of.
    In addition, the hub 11 has a tap to which other devices can connect to each port (Port1 to Portn), and when the connected device needs power, the hub 11 is controlled by the control signals of the plurality of controllers 1 to n. It receives power from PC 10 and supplies it to the devices connected to each port (Port 1 to Portn).
    At this time, the present invention is connected to the control unit (1 ~ n) corresponding to each port (Port 1 ~ Portn), unlike the prior art each port (Port 1 ~ Portn) by the control signal of the plurality of control unit (1 ~ n) It is different to apply different power to the devices connected to it.
    That is, regardless of a hub having a bus power or a hub having a magnetic power, the hub 20 has a control unit 1 to n so as to correspond to each port (Port 1 to Port n) so as to supply data and different power. Supply to devices connected to the ports (Port 1 to Portn). First, switch SW of the controllers 1 to n is turned off, and a universal serial bus device is connected to each port (Port 1 to Portn). After installation, the device can operate as it is if the device has a magnetic power. If the device has a bus power, the power is supplied by turning on the switch (SW).
    In this case, the buffers BUF of the controllers 1 to n are positioned in front of the ground GND signal to prevent backflow of power to prevent jittering.
    As described in detail above, the present invention is equipped with both a universal serial bus device having a magnetic power and a universal serial bus device having a bus power to a hub of a universal serial bus. In addition, there is an effect that can prevent jitter of the power source that can occur when switching switching.
